It'd be a physical change. This is because it's a change in the state of matter and not altering the chemical structure of water
<span>they both had their conclusions based on solid evidence</span>
Imagine we have <span>mass of solvent 1kg (1000g)
According to that: </span>
= 4.8 mole * 98 g/mole = 470g
m(H2SO4) which is =<span>470g
</span><span>m(solution) = m(H2SO4) + m(solvent) = 470 + 1000 = 1470 g
d(solution) = m(solution) / V(solution) =>
=> 1.249 g/mL = 1470 g / V(solution) =></span>
An apple should be cut into 4 equal pieces, then put each slice in a separate container and label accordingly with letters A, B, C, and Control. Put water, ginger ale, and lemon juice into containers A, B, and C respectively but leave the Control untouched. Observe which of the slices in containers A, B, C will stay the same color after the one in control turns brown, if the slice maintains its color then the liquid added prevents an apple slice from browning. The variables are the liquids added and the control is the slice that did not have anything added to it.
Answer:
C. The product must solve the problem for which it was designed.
Explanation:
Technological design is the study, development and application of technological process with the intent of designing a product to solve required problem.The process could be based on the use of a computer.
Generally, technological process and development always tend to design a problem solver product. Through this process, more new technologies are produced.
Therefore in technological process, the product must solve the problem for which it was designed.
